Decorative stud setting tool

ABSTRACT

The stud setting tool comprises three coaxially nested cylinders of different diameters such that three different sizes to studs may be inserted by the one tool by selecting a particular cylinder for holding the stud. A sleeve telescopically passes through the outer cylinder to connect rigidly to the second cylinder and a plunger in turn passes through the sleeve and couples with the third cylinder. The arrangement is such that a large sized stud held by the outer or first cylinder can be ejected by the movement of the sleeve within the first cylinder to cause the second cylinder to push the stud free of the first cylinder. An intermediate sized stud held in the second cylinder in turn, can be pushed free of the second cylinder by the plunger within the sleeve. Finally, a small sized stud held in the third cylinder can be freed by this third cylinder sliding along the end of the plunger.

Decorative metallic members secured to garments are referred to in the art as both studs and as nails." Generally, the nail type of decorative fastening will have a flat head whereas the stud will have a slightly rounded or convex head. Other shape heads of course may be provided. In any event, for purposes of the present application, the term stud is meant to include decorative nails or decorative metallic members of various different shapes provided with points for securement to a garment.

BACKGROUND OF THE INVENTION It has become common practice to provide decorations in the form of metallic studs on materials and particularly on articles of clothing such as blue jeans and the like. While such studs can serve a dual function, such as is the case in upholstery for furniture wherein the stud actually secures portions of the material together as well as provides a decorative effect, when used on clothes, the primary function of the stud is purely decorative in nature and large numbers may be secured along or adjacent to seams or along other baste lines.

Many individuals would prefer to form their own decorative designs with such studs or nails and it is with this end in view that the present invention is most applicable.

Normally, the stud is provided with points in the form of integral prongs extending from the relatively flat head portion. In attaching the studs to material, the prongs are simply pushed through the material and then bent preferably inwardly to secure the stud in place.

Such an operation can be accomplished by a stud setting tool wherein the stud is held for example in the mouth of a cylindrical member and a plunger or the like within the cylindrical member then used to engage the surface of the stud and push it free of the cylindrical member to cause the prongs to pass through the material and against the anvil portion, thereby effecting the desired bending of the stud points. Any such tool of this design, however, is limited to a single sized stud and thus lacks versatility.

BRIEF DESCRIPTION OF THE PRESENT INVENTION With the foregoing in mind, the present invention contemplates an improved stud setting tool so designed that the same tool can be used to insert studs of different sizes; that is, studs of different head diameters. Provision of such a tool greatly expands the types of decorative patterns and types of studs which can be used by a person in attaching studs to his or her own clothing.

Briefly, the invention contamplates in its preferred form, first, second and third cylindrical members of progressively decreasing first, second and third internal diameters respectively, arranged in coaxial nesting relationship. While in its broadest aspects, there need be provided only two cylindrical members, the provision of three members permits three different sizes of studs to be inserted by the single tool, the internal diameters of the members corresponding to the diameters of the three differently sized studs.

An elongated sleeve passes axially through the first cylindrical member rigidly connect to the second cylindrical member. A plunger in turn passes axially through the sleeve to terminate within the third cylindrical member, the third cylindrical member being slidable along this end of the plunger.

The foregoing arrangement is such that a stud of given diameter may be held in the first cylindrical member and ejected by movement of the sleeve causing the second cylindrical member to engage and push the stud free of the first cylindrical member. Alternatively, a stud of smaller size may be held in the second cylindrical member and pushed free by the end of the plunger by telescoping movement of the plunger. Finally, an even smaller sized stud may be held in the third cylindrical member and pushed free by the plunger as a consequence of telescoping movement of the third cylindrical member along the end of the plunger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIG. 1, the stud setting tool includes first, second and third cylindrical members 10, 11 and 12 respectively of progressively decreasing first, second and third internal diameters respectively, arranged in coaxial nesting relationship. Only the extreme end of the third cylindrical member 12 is visible in FIG. 1.

An elongated sleeve 13 has an increased diameter portion 14 defining an annular shoulder 15 spaced from the first cylindrical member 10 as shown. A first end of the sleeve 13 is shown at 16, the second end telescopically extending into the first cylindrical member 10 to rigidily connect to the second cylindrical member 11, all as will become clearer as the description proceeds.

A plunger 17 has a first end terminating in a plunger head 18 and a second end passing into the sleeve 13 to terminate within the third cylindrical member 12 as will also become clearer as the description proceeds.

As shown in FIG. 1, there is provided a first spring means 19 positioned between the plunger head 18 and the first end 16 of the sleeve serving to bias the plunger head axially away from the first end 16 of the sleeve.

Adjacent to the lower end of the first cylindrical member is shown an anvil 20 defining a concave surface 21. Also illustrated in exploded view is a first sized stud 22 provided with points 23. As indicated by the dashed line, the stud 22 is arranged to be held, for example, in the first cylindrical member 10 for setting or insertion in a piece of material such as illustrated at 24 normally positioned between the tool and the anvil surface 21.

FIG. 2 illustrates three different sized decorative studs, the largest being indicated at 22 and corresponding to the stud 22 described in FIG. 1. This stud has a given diameter D1 which corresponds to the internal diameter of the first cylindrical member 10 of FIG. 1.

Below the stud 22 there is shown a second sized stud 25 having a decreased diameter D2 corresponding to the internal diameter of the second cylindrical member 11 of FIG. 1.

Finally, there is illustrated at 26 a third decreased sized stud of diameter D3 corresponding to the internal diameter of the third cylindrical member 12 of the tool in FIG. 1.

Further details of the tool will be evident by now referring to FIGS. 3, 4 and 5. I

Referring first to FIG. 3, the second end of the sleeve 13 is indicated at 27 and shown rigidly secured to the second cylindrical member 11. It will also be evident from FIG. 3 that the first cylindrical member 10 can slide along the surface of the sleeve 13, this motion being limited by the annular shoulder 15 defined by the enlarged diameter portion 14. In FIG. 3, the cylindrical member 10 is shown in an intermediate position merely to illustrate that sliding movement can take place. Normally, it would be resting on the end 27 of the second cylindrical member under its own weight unless manually retracted by the operator.

Also in FIG. 3 there is shown the second lower end of the plunger at 28 terminating within the third cylindrical member 12. As is evident, the third cylindrical member 12 is arranged to slide along the second end portion of the plunger. A second spring means 29 is positioned between a stop member 30 forming a portion of the second end of the plunger and the third cylindrical member 12 is bias the third cylindrical member 12 axially away from the stop portion 30. A further stop 31 at the lower end of the plunger prevents the third cylindrical member 12 from being biased completely off the end of the plunger and defines with the stop 30 the axial distance of sliding movement of the third cylindrical member 12 along the second end portion of the plunger.

In the specific embodiment disclosed for illustrative purposes, it will be noted that the extreme end of the plunger is provided with a tapped bore 32. This tapped bore is provided so that attachments may be secured which can serve to hold even smaller sized studs or hold other attachments if desired.

In FIG. 3, the stud 22 referred to in FIG. 1 is shown fricitionally retained within the first cylindrical member 10 preparatory to being inserted or set into the material 24.

FIG. 4 shows the relative positions of the cylindrical members during an inserting operation for the stud 22 and FIG. 5, as described heretofore, illustrates a setting operation for the smaller sized stud indicated at 26 corresponding to the stud 26 of FIG. 2.

OPERATION The operation of the stud setting tool can best be understood by referring in detail to FIGS. 4 and 5 relative to FIG. 3.

Assuming that the largest sized stud 22 is to be inserted, it is initially positioned in the end of the first Cylindrical member 10 as described in conjunction with FIG. 3. The material 24 is then positioned over the anvil surface 21 and the entire tool together with the stud brought down on top of the material.

By urging downwardly on the plunger 18, the spring 19 acting on the first end 16 of the sleeve 13 will cause the second cylindrical member 11 to engage the surface of the stud 22 and push it free of the first cylindrical member 10, this first cylindrical member 10 sliding upwardly along the sleeve 13 when its lower end engages the work. The downward force will cause the points or prongs to bend inwardly by engagement with the concave surface and thus lock the stud 22 to the material.

In the event a different sized stud such as the intermediate sized stud 25 shown in FIG. 2 were to be inserted, this stud would be held in the second cylindrical member 11 the first cylindrical member 10 being telescoped back along the sleeve 13 as shown in FIG. 4. Actually, this telescoping movement would result from the lower end of the cylindrical member 10 engaging the work or alternatively, the cylindrical member 10 could be slid back out of the way by the operator's other hand. Further downward movement of the plunger 18 would then result in the end of the third cylindrical member 12 engaging the intermediate sized stud to push it free of the end of the second cylindrical member 1 1.

FIG. 5 illustrates the manner in which the smallest sized stud 26 of FIG. 2 is inserted wherein initially, the stud 26 is held within the third cylindrical member 12. Thus, complete telescoping movement of both the plunger and the sleeve such that the plunger head 18 engages the first end 16 of the sleeve and the annular shoulder 15 of the sleeve engages the first cylindrical member 10 exposes the third cylindrical member 12 so that it can be inserted over the smallest sized stud 26. In this respect, the cylindrical member 10 can be manually retracted by the operators other hand to hold it along with the sleeve 13 and second cylindrical member 11 in the retracted positions shown in FIG. 5 to expose the third cylindrical member. Forcing of the stud against the material will then result in the third cylindrical member 12 telescopically sliding upwardly on the second end against the bias of the second biasing spring 29 so that the extreme end 28 of the plunger will push the stud 26 free of the third cylindrical member.

In any one of the previously described three instances, the points of the stud will be forced inwardly or bent inwardly by the force exerted on the stud by the tool against the concave surface of the anvil 20. When the tool is lifted from the anvil, the first and second springs will return the various components to their initial positions illustrated in FIG. 3.

From the foregoing, it will be evident that the present invention has provided a greatly improved tool particua. a first cylindrical member having a first internal diameter corresponding to the diameter of a first sized stud for holding the stud;

b. a second cylindrical member having a second internal diameter lesser than said first internal diameter for holding a second smaller sized stud, said second cylindrical member being coaxially nested within said first cylindrical member;

0. a sleeve passing through said first cylindrical member to rigidly connect to said second cylindrical member; and,

d. a plunger passing through said sleeve to terminate within said second cylindrical member whereby a stud held in said first cylindrical member can be ejected by telescoping movement of said sleeve through said first cylindrical member to cause said second cylindrical member to engage said stud and push it free of the first cylindrical member and whereby a smaller sized stud held in said second cylindrical member can be ejected by telescoping movement of said plunger through said sleeve to cause the end of the plunger to engage said smaller sized stud and push it free of said second cylindrical member.
